IMPORTANT: Attach Antenna Before Powering On!
Always connect an antenna to your device BEFORE plugging in USB or turning it on. Transmitting without an antenna can permanently damage the LoRa radio chip. Even a few seconds of transmission without an antenna can cause irreversible damage. This applies to flashing AND normal use.
